feed.php bug

[dryoo]

In search mode, if someone put large query utf-8 string, Server process may suffer time out.

like this.

I tested on my development DokuWiki (with a few pages only), and the speed looks normal. May we know the server environment and the number of pages you have in total?

I currently disabled feed.
but i will test again.

my server status is below.

Intel(R) Xeon(R) CPU E3-1231 v3 @ 3.40G

Ubuntu 16.04.2 LTS, PHP 7.0.15-0ubuntu0.16.04.4 (cli) ( NTS ), Nginx, MariaDB

total pages : 10779
total media : 13858

I see. Search in feed.php is a full text search. Do you experience slowness using the search on the webpage UI (it's also a full text search)?

Oh. I use currently google custom search.

but I tested dokuwiki's own search engine.
and
The answer is Yes.

then is this not a problem of feed.php?

I think normal user will not use such query. but crawling bot uses that frequently.

OK, it's just that you have too many content in your wiki and the native search should take that much time. Also the search indexes may not work with Unicode string well.

You may want to disable search functions as well, besides your already disabled feed.

⭐️ Looks like search in feed.php does not respect disableaction=search; should we enhance this a bit?
